check_snmp_time.pl
This plugin checks the remote servers time and compares it against the local time on the Nagios server. With Nagios being sync'ed to NTP, this can identify systems that have no NTP set up, or NTP is wrongly configured. This plugin is particalry helpful if SNMP is already used to monitor the system.
The plugin depends on Perl's Net::SNMP package, i.e. perl-SNMP-5.3.0.1-25.34.1.
Usage:
check_snmp_time.pl [-v] -H <host> -C <snmp_community> [-2] | (-l login -x passwd [-X pass -L <authp>,<privp>]) [-p <port>] [-o <tz-offset>] -w <warn level> -c <crit level> [-f] [-t <timeout>] [-V]
Options:
-v, --verbose
print extra debugging information
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-C, --community=COMMUNITY NAME

-P, --port=PORT
SNMP port (Default 161)
-o, --tzoffset=MINS
the remote systems timezone offset to the Nagios server, in minutes
-w, --warn=INTEGER
warning level for time difference in seconds
-c, --crit=INTEGER
critical level for time difference in seconds
-f, --perfparse
Perfparse compatible output

Plugin Usage Example:
The plugin with its most basic use.
susie: ~ # cd /srv/app/nagios/libexec susie: ~ # ./check_snmp_time.pl -H 192.168.98.109 -C NBNro -w 1 -c 20 192.168.98.109 clock is accurate to the second : OK
The plugin with the -f option, returning additional performance data.
susie: ~ # cd /srv/app/nagios/libexec susie: ~ # ./check_snmp_time.pl -H 192.168.98.109 -C NBNro -w 1 -c 20 -f 192.168.98.109 clock is accurate to the second : OK | local=2010-12-14_19:27:26 remote=2010-12-14_19:27:26 offset=0
